I've been waiting for my banner ads to go live for over a week now. Sent my payment on 16th June to this address 1Myf1Scb8xGPSa7YYciMCANpQkjdgGWNh3.
Apart from OP's payment, the above address received another 8.55 BTC on Jun 17.
It seems there is another victim.

what can i do? anything??
I am sorry for your loss, but I believe there is pretty much nothing you can do to get the money back.
You may report to the authority, but it is very unlikely it will end well.
The scammer is possibly behind proxies and tor, and the bitcoin will probably go through a mixer...
